Tsochilus Langlassei with floral analyses made under the 
direction of Dr. Schlechter and an actual fragment of the 
type number in the Ames Herbarium, it appears to be 
the wise course to reduce this concept to the synonymy 
of the widespread J. linearis. While it is described as a 
smaller plant than J./inearis, the leaves of I. Langlassei 
(in the duplicate type) are up to 8.6 cm. long and well 
within the length of those of J. linearis as described from 
the West Indies and Brazil and are closely similar to the 
leaves of Hpidendrum lineare as figured by Jacquin. The 
floral parts of I. Langlassei closely approximate those 
represented by Cogniaux for the Brazilian form of I./in- 
earis.
